This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. Start the engine and put your finger over the naked purge valve port. Fuel tank vapors are allowed to move from the fuel tank, due to pressure in the tank, through the v P0496 code.

At this point the purge valve should be closed.
Those codes disappeared and the other three codes P04xx remained. Refer to Fuel Tank Pressure Sensor Replacement. Unhook the electrical connector and the vacuum line's to it. I actually have something to add now, the Bluetooth dongle with the android torque app is an amazing combo. When you blow threw it air does pass all the way through the solenoid. Did you complete the replacement? Should I go ahead and replace it too? Here are some of the most common. There is a a great YouTube video on diagnosing the problem below.

At ten years of age, you may have corrosion and sticking in the vent valve, which would cause problems with purging.
Unplug the vent line that goes from the back of the valve to the fuel system. Now when I put gas in it I still get the 496 code and its hard to start after putting gas in it.
